Technical description
Network nodes WTT56.. receive and process data from consumption metering devices (maximum 500) within the AMR system. Up to 12
network nodes can communicate with one another and exchange the respective consumption values (mesh system).
Components WTT56..
The network node WTT56.. is made up of the following components:
Power supply:
Memory
500 measuring devices
Backup battery
Transmitter and receiver are used for recording the data from con-
sumption metering devices and forwarding these to other network
nodes in the same network. The data memory contains the meas-
uring data from the consumption metering devices. It is protected
against temporary power failure, for instance during replacement of
the main battery, by the backup battery. Local network readout can
take place via the M-Bus interface (an M-Bus load).
Keys
The network node has 3 keys with the following functions:
DISPLAY Key (10) for switching over the display and acknowledging faults.
MODE Key (9) for switching installation mode on or off. If an extended mode is active, this key is pressed to return to the standard mode.
RESET Recessed key (7) for triggering a network reset (interruption of all connections between the network nodes).
